SPECIFICATION forming part of Letters Patent No. 3572,751, datedNovember 1.6, 1886.f Application filed February 9, 1886. Serial No.`191,301. (No model.)

i accompanying drawings, and to the letters of reference marked thereon,which forma part of this specification.

The objects of my invention are, first, a convenient and symmetricalarrangement of the window frame and vnish for use with sliding blinds;second, to facilitate the movement'of the sliding-blind sections, and tocause them to remain in whatever position they are left; third, tosuitably incase the blind weights;

fourth, to utilize the blindway-strips as part1 of the weight-box andthe weight-box asparts of the interior finish; fifth,without additions,

to make customary parts of the window frame and nish serve also forblindway-strips and weight-box; sixth, to withdraw one or more of theblindsections from the face of the window; and, seventh, to diminish orrelieve the apparent projection of the blindway-strips into the room infront of the plaster. These ends I attain by the peculiarities ofconstruction and arrangement hereinafter se't forth in detail.

In the accompanying drawings like letters of reference designate thesame or similar parts in the several figures.

Figure lis an interior elevation of a win.-

dow to which my improvements are applied,

a portion of the casing or iinish being cut away at one side to disclosethe method 'of counterbalanc-ing the blind-sections. Fig. 2 isahorizontal section of the same on the line x x, Fig. l.y Fig. 3 is avertical section thereof on the line y `y, Fig. 1. Figs. 4 to 8,inclusive, are horizontal sections of one side of a windowframe andparts therewith associated, illustrating the details and modications bywhich my improvements are applied in variousways to'differentconstructions; and Fig. 9 is a de- `eral constructions shown.

vis found at the sides of the window, as shown tail view, on agreatly-enlarged scale, of one of the springs applied to theblind-sections.

It is obvious that sliding blinds possess the advantage over foldingblinds of not projecting into the room and interfering with draperies,and of not clashing with each other where windows are placed neartogether, and that any improvements therein .by which greater oradditional advantages will be at-V tained must be desirable.

Referring to Figs. 1,- 2, and 3, Sheet 1, L L represent a series ofblind-sections, each eX- tending from one side of the window to theother, and arranged to slide freely up and down in the blindwaystrips GC, grooved to -receive and retain the edges or sides of said sections. EE are counterbalancing-weights, preferably made of. cast or wroughtiron, attached to the blind-sections at eachside by means of cords orchains running over pulleys a a, set in the grooves of said blindway'-strips C C. The weights E E are incased land run in boXe's formed byinclosingaspace available, or formed for that purpose, in* the sev- HHare L-shaped metallic strips secured in an upright position inside ofsaid Weight-boxes, so as to separate said weights E E, prevent theirclashing, and thereby' insure the smooth running of the blind-sectionswith which-they are connected. The number of blind-sections employed canbe varied as desired to suit the demands of individual cases.

Ordinary dry white-pine blind-sections will weigh about a pound to asurfacefoot. It requires,aecordingly,in each weight-boX,to bal-4 ance ablind-section of the usua1size,a weight iive-eighths by one andone-eighth of an inch by one foot in length, ample room for which in theseveral arrangements illustrated in the drawings. Removable sections aremade in the weightboxes, preferably in the blindwaystrips C C, forming apart thereof', in order to reach or get at said weights E E whendesired. B B are the window-sashes, F F, window-` jambs,and G G theinside easing. At the bottom of the Window I form a pocket for thereception of the blind-,sections by setting the I, panel M, which is acommon part of the winibo dow-finish in buildings of the better class,forward sufficiently to make room for said blindsections behind it. Asimilar pocket may be formed at the top of the window to receive theblind-sections,or a pocket may be provided at the top and bottom of thewindow and a part of said blind-sections arranged to run into one and apart into the other.

Referring to Figs. 2 and 4, the jamb F is eX- tended forward and groovedto form the requisite runways for the blind-sections. The weights E Erun in a space easily made for them in ordinary constructions bystopping the lath and plaster at the inner side of the adjacent stud, asshown. The requisite width of blindway and of weight-boxes for foursections with their counterbalanciug-weights E E is obtained,where twoby six inch studding is used, by setting the casing G ont from the wallor plaster and finishing the space between its outer edge and the faceof said wall or plaster with the back piece, N.

. In Fig. 7 the blindway-strip C takes the place of the jamb-liningcommonly employed in brick and stone buildings, and the weights E E areinclosed by said blindway-strip and the casing G in a space commonlyleft in such buildings in front of the Window-frames.

The construction shown in Figs. 4to 7, inclusive, possesses theadvantage of requiring no more parts than are necessary to finishwindows where inside blinds are not used.

`In Fig. 5 the blindway-strip C and easing G are arranged to form withthe back piece,N, a box of sutlicient size to accommodate two weights.Should three blind-sections be required, the upper section, which is notmuch used, may be held in place by springs or cams in the ordinary way.With this arrangement the windowjamb and sash-stop arel constructed inthe usual manner.

In the arrangement shown in Fig. 6 the casing G is set out from the wallor plaster sufficiently to accommodate back of it weights for `threeblind-sections, and its inner edge overlapping the front edge of theblindway-strip C forms a part thereoil-viz.,a side of the front groove.

Fig. 8 shows an arrangement of the blindway-strip C and weight-boxadapted for use with three blind-sections and their counterbalan'cing-weights. rIhe weight-box projects into the room beyondthe face of thewall or plaster,

`and the apparent projection is broken and relieved by arranging theinterior window-flul the plaster is filled and finished by the backpiece, N.

-In the several constructions in which the weight-box is set in front ofthe window-frame, as shown in Figs. 5, 6, 7, and 8, the blindway--strips C and-casing G may be made andput upl independently of thewindow-frame, and the several constructions shown in the drawings, inwhich the blindway-strip C, to accommodate the desired number ofblind-sections, or

casing and the plaster is closed and finished by a back piece, N, notonly furnish convenient inclosures for the requisite blind-weights, whenthey are employed, or the cords of connected counter balancingblind-sections, but alsol 4serve to diminish or relieve the apparentprojcction of the blindway-strips into the room. To insure the smoothrunning of the blindsections L L in the blindway-strips C C and topermit of their easy removal therefrom, I attach the light springs u nto one edge or -side of said blind-sections, as shown in Figs. 1 and 9.These springs n n are preferably formed as shown most clearly in Fig. 9,and are rigidly secured at one end to the edge of the blind-sections(recessed to receive them) and adjustably attached thereto at the otherend by screws g, which mayserve also as fastenings for the weight-cords.

Those arrangements in which the blindway strips C C are located in frontof the plaster, as shown in Figs. 5, 6, and 8, possess this advantage,that the blind-sections will clear the walls when opened or withdrawn,and the window may be entirely uncovered, without pockets or receptaclesto' receive said sections, as hereinbefore described.
